The Telomeric Repeat-containing RNAs (TERRA) participate in the homeostasis of telomeres in higher eukaryotes. Here, we investigated the expression of TERRA in Leishmania spp. and Trypanosoma brucei and found evidences for its expression as a specific RNA class. The trypanosomatid TERRA are heterogeneous in size and partially polyadenylated. The levels of TERRA transcripts appear to be modulated through the life cycle in both trypanosomatids investigated, suggesting that TERRA play a stage-specific role in the life cycle of these early-branching eukaryotes.

Resveratrol (RSV) is a nutraceutical compound belonging to the nonflavonoid polyphenol family, whose antioxidants, anti-inflammatory, and antitumoral properties have been widely investigated. The ability of RSV to provide beneficial effects for neurological, cardiovascular, and cancer disorders rekindled the interest to explore the molecular mechanisms behind its pleiotropic effects, which are due to the modulation of coding and noncoding genes involved in many key biological pathways. With a computational approach, including docking studies and thermodynamics calculations followed by 200-ns-long molecular dynamics and a clustering analysis, we hypothesized the stabilizing binding between RSV and G4 structures of telomeric repeat-containing RNA (TERRA), which is a tumor-suppressive long noncoding RNAs (lncRNA) involved in the regulation of telomere maintenance.
